Women of China 1994年第1期 16-17页

作者： ZHAO HONGMEI and MENG xiaodong MAN SUJIE

SEEING off her youngest daughter, zhang Xiling, in her fifties and tired, leaned against a low, old and dilapidated house made of mud. The little hill village looked very quiet at dusk; the hilly road in the evening glow zigzaged further away. This common rural woman stared at the hilly road where she watched her dreams go as all her children went away one by one. In 1978, Nie Wenhai, her oldest son, was admitted to Harbin Col-

林木根系通过摩擦锚固作用实现对土体的固持。以冀西北地区白桦的根系为对象,通过垂直拉拔试验,探究根径、根系土中埋深、土壤含水率、海拔、根系生长方向等因素对根系-土壤界面摩擦性能的影响。结果表明:根土摩擦力随着埋深、根径的增大而增大,同根系直径满足幂函数关系,决定系数大于0.82,拟合良好;土壤含水率由11.85%增大至17.85%,根土摩擦力先增后减,最大拔出力对应土壤含水率范围在13.85%~17.85%之间;不同海拔位置、不同生长方向的根系,其根土界面摩擦力也有所差异。冗余分析结果表明,根系直径和海拔对根土摩擦力贡献接近且较高。研究结果对冀西北地区林木树种的选择和生态环境的保护具有重要的意义。

考虑风电机组控制参数相互耦合,为解决控制参数不精确以及控制目标难以兼顾问题,提出一种基于塔架主动阻尼控制的自适应变速控制参数优化方法。首先,基于转矩-转速系统和塔架侧向主动阻尼控制完成数学和动力学建模,并计算主动阻尼增益初始值。其次,为便于整定PI控制参数和分析计算,针对惯性较大的转矩-转速系统采用Routh法将其辨识为低阶惯性系统,进而采用时间加权绝对误差积分准则整定变速系统PI控制参数初始值。最后,为保持最优控制状态,基于灾变遗传算法优化各风速点变速系统PI控制参数和主动阻尼增益,并将其分别与风速拟合构建自适应控制。算例分析通过比较频域特性、控制精度、塔架振动和载荷情况验证了所提方法的有效性。

针对某款并联式混合动力汽车(PHEV),以整个循环工况的燃油经济性最优为目标,运用离散动态规划算法,得到PHEV的全局最优控制策略。并通过在逆向计算中设置不满足条件的控制变量的收益函数为无限大的方法,来达到电池荷电状态平衡。最后建立Matlab/Simulink仿真模型,对获得的全局最优控制策略进行仿真验证,并与采用瞬时最优控制策略得到的仿真结果进行比较。结果表明,全局最优控制在满足电池荷电状态平衡的前提下,获得了比瞬时最优策略更好的整车燃油经济性。
